Slack × ChatGPT

Use the Slack MCP server
in ChatGPT

Search messages, post to channels, and read your Slack workspace from your AI. This guide connects Slack to ChatGPT (chatgpt.com) through a governed gateway — one URL that also works in every other MCP client you use, with your rules and a full log attached.

Connect Slack free

Live-probed · Security-scanned · Note: Slack currently restricts third-party sign-ins — API-key path recommended

Setup: Slack in ChatGPT

ChatGPT adds MCP servers via custom connectors in developer mode. The gateway route takes about two minutes:

  1. Connect Slack to your free gate gateway from the verified directory.
  2. Open ChatGPT → Settings → Connectors and enable Developer mode under Advanced.
  3. Click 'Create', name it 'gate', paste your gateway URL, and set authentication to OAuth.
  4. Approve the authorization — Slack is now available in your ChatGPT conversations.

What to ask once it’s connected

“Summarize #support since yesterday.”
“Find the thread where we decided on the pricing change.”
“Post these release notes to #general.”
“What did I miss while I was out?”

Why route it through a gateway

One URL, every client

The same Slack connection works in Claude, Claude Code, Cursor, VS Code too — no per-client re-wiring.

Rules before regret

Allow, ask, or block every tool Slack exposes — reads can flow freely while writes require your approval.

Every call logged

A plain-language activity log of everything ChatGPT did with Slack — searchable, exportable, auditable.

Scanned and probed

Slack passed a live handshake probe and a security scan before listing — and drift detection watches it after you connect.
